SAFETY-RAZOR Filed June 11, 1932 7m.- 6. TAYLOR Patented Apr. 17, 1934 PATENT OFFICE SAFETY RAZOR George Taylor, Hollinghurst, Kingsway, Penwortham, Preston, England Application June 11, 1932, Serial No. 616,713 In Great Britain September 22, 1931 12 Claims. (CI. 30-12) This invention relates to asafety razor provided with the known device of a face roller, which when applied to the face causes a reciprocation of a carrier for the blade.

Heretofore, in such safety razors the blade carrier has been mounted to slide on a plurality of longitudinal bars or a plurality of feet have been provided on the carrier at each end, the feet sliding in grooves in the razor frame.

The object of the present invention is to improve on the known reciprocating razor by providing a single axial support for the carrier and setting guides which position the carrier so as to guide the operative edge of the blade in set position with respect to the face roller. In such a construction friction is reduced to a minimum as the support and the guides require only a small superficial area, accuracy of setting is ensured and maintained even when wear occurs and adjustment of the setting may be effected, and the whole razor rendered. more simple, compact and easier to construct than hitherto. A further object is to construct such a razor so that its detachable parts shall be readily dismantled for changing the blade.

The accompanying drawing shows the invention applied to a razor employing a wafer blade which is adapted to be bent into curved form when mounted on the razor.

Referring to the accompanying drawing:-

Figure 1 is a side elevation showing the complete razor with handle,

Figure 2 is a plan of Figure 1 with the blade and backing plate removed,

Figure 3 is an enlarged view of about double the full size upon the line AA of Figure 1,

Figure 4 is a detailed view showing the blade set and guided by the end plates, and

Figure 5 illustrates a double edged blade of the usual character.

Figure 6 is a detail end view with parts omitted, of a modification wherein the single pivot for the carrier is of rectangular cross-section.

In carrying out the invention according to the forms illustrated in the drawing a double edged blade, for example as shown in Figure 5, is attached to a carrier 1 by means of the curved backing plate 2, provided, as usual, with steady pins adapted to enter the holes 3 of the carrier 1 and attached thereto by means of the hollow screw 4 threaded to the projecting stem 5 attached to the backing plate 2.

The carrier 1 is supported by a single axial support at the center constituted by pivot rods 20, 21, adapted to slide respectively in end frames 14 and 15 about which rods the carrier is adapted to tilt. On the carrier is provided a pin 6 working in the groove '7 of the face roller 8 and the carrier is shaped as regards its top face 9 so that as the backing plate 2 is drawn downwards by 6. the action of the screw 4 the blade 10 is pulled down hard upon the edges of the surface 9 and bent to the form shown in Figure 3, whereby its operating edge 11 is brought by the action of the setting guide lugs 12 into a correct setting with regard to the roller 8 so as to give the necessary shaving angle.

It will be seen that the guide for the carrier and the blade is achieved by means of the upstanding lugs 12, 13 forming part of the end frames 14, 15. By means of the reduced surface provided by these lugs 12, 13 very accurate setting of the blade may be achieved so that it only rests lightly thereon during reciprocation, and moreover a relatively small friction surface is presented to the blade during its movement. An adjustment of the set of the blade is provided by these lugs in as much that they may be filed to bring the operating edge 11 nearer to the face roller 8. In place of the lugs upon or adjoining the end frames 14, 15, the upper periphery of each frame may be so shaped that the edges of the blade rest lightly thereon, as shown in Figure 4:, in which case no upstanding lugs are needed. It will be seen that the shape of an end plate, for example 14, is such 35 that when resting on the surface as regards the edges of the blade the central portion thereof is preferably free from the said surfaces for the purpose of reducing friction.

16 is a roller provided along the inoperative edge of the razor as a safety guard therefor.

To control and limit the tilt of the carrier 1 when the blade is removed upstanding pins, such as 17, 18, are provided, attached to the cross plate 19 so that the pin 6 has a slight play in the groove '7 but cannot come out of engagement therewith. When the blade is mounted on the carrier the pins do not engage therewith so that the carrier 1 can be moved with very little friction and guided by the contacting surfaces of the blade 10 with the setting guides on the end frames.

In place of the pins 17 and 18, to limit the tilt of the carriage 1 the pivot of the carrier may be constituted by rods 20a of rectangular cross section as shown in Figure 6 instead of circular, and projecting one from each end of the carrier as in the preceding figures, the holes in the end plates being also of rectangular cross section but slightly larger than the rods 20a so as to permit a slight tilt when the blade is removed, r

By providing a tilting carrier in association with the setting guides, the blade is permitted to take up automatically its correct setting when being mounted on the carrier, and moreover adjustment of the setting can also be effected as above described, the whole construction being extremely flexible, simple and accurate.

In a" modification the pins 17 and 18. may engage the carrier and the setting guides on the end plates may be omitted. To permit of access to and manipulation'of the central screw 4, the; end frames l l and 15 are connected to a handle 22 by means of a bridge piece 23 which embraces the central screw 4 as shown, the handle pref-' erably being a separate integer which is screwed into the bridge piece.

The invention provides an effective means of achieving the desired result of a razor blade which reciprocates while in contact with the face, at the same time that it is carefully guided so that no harm can come to the user and the shaving is thus facilitated and improved in effect.

Inplace of the roller 14 a sharpening surface for the inoperative edge of the blade 10 may be arranged; this construction is the subject of my co-pend-ing application for a patent No. 616,714.
